cold shady dry spot, need a lovely climber

Round the back of my house there's a trellis that goes from a cold shady dry spot (north-facing) up to a paved area that's quite sunny - midday to afternoon, full sun (west facing). What can I put there that'll climb up and give me colour - and scent too, if possible, in the summer? I imagine sitting there basking and enjoying a completely slug-free garden.... LOL

Oooo. I think climbing hydrangea at the shady end would be lovely. They are pretty slow growers though.
Clematis like to have shady roots but sun on their leaves.
Climbing roses would need at least 6 hours of full sun a day to flower properly but would be good at the sunny end.
Virginia creeper will grow like a weed but doesn't really have much in the way of flowers and fragrance. Lovely colour in the fall.
What about a trumpet vine?

I'd go for a clematis, who likes its feet in the shade and the rest of it in the sun. Likes an alkaline soil. There are so many species of clematis and loads of books. Check out amazon. I'd forget about a rose. Although they do claim that Zephyrine Drouhin (the thornless rose) likes a northern exposure (meaning no sun). Maybe there is a climbing version.

Thanks everyone - I thought Zephirin Drouhin needed sun - but if not, that 's top of my list. Which honeysuckle has the best scent? Never thought of climbing hydrangeas. That sounds good. Do hydrangeas and clematis have scent? Should I dig a bean trench type of space for them? ( the ground is compacted builder's rubble and clay subsoil - Yay!)
